Communication with a communication terminal becomes possible.

The best mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described in detail with reference to the drawings.
(First embodiment)
First, the first embodiment will be described.
(Constitution)
The first embodiment is a communication system to which the present invention is applied.
FIG. 1 shows a communication network on which a communication system is used.
As shown in FIG. 1, a communication network that can be used by a mobile device (mobile phone terminal) 1 is constructed by a plurality of networks. At least a 3GPP network (PS domain network compliant with 3GPP) 100, a WLAN (Wireless Local Area Network) ) 200. The fixed telephone network 300 is not essential in the communication network, but in this example, the fixed telephone network 300 is added.

FIG. 2 shows a telephone number assigned to a mobile device (mobile phone terminal) 1 that can be used in the mobile network constructed as described above.
As shown in FIG. 2, the mobile device 1 has a unique telephone number (090-xxxx-xxxx (090 number)) used in the 3GPP network 100 and a unique telephone number (050-zzzz-zzzz (050) used in the WLAN 200. No.)) (communication (outgoing and incoming)) is possible. Furthermore, the mobile device 1 can use a communication service (hereinafter referred to as a one-number service) using a representative number (for example, 0A0-yyyy-yyyy (0A0 number)) that can be used in the 3GPP network 100 and the WLAN 200. . As a result, the user can make a call (call) with the representative number (0A0 number) from any of the 3GPP network 100 and the WLAN 200 to identify himself / herself (other communication terminal). it can.

FIG. 3 shows a configuration of a communication system in the 3GPP network. This communication system is basically configured to be compatible with the 3GPP network, and is configured to be able to communicate with a representative number in addition to the telephone number (090 number) of the 3GPP network.
As shown in FIG. 3, the communication system includes a mobile device (mobile phone terminal) 1, a processing server 2, an SGSN (Serving GPRS Support Node) 3, and a GGSN (Gateway GPRS Support Node) 4.

  As described above, a representative number (0A0 number) is assigned to the mobile device 1 in addition to a unique telephone number (090 number, also referred to as a child number in the following description) of the 3GPP network. The mobile device 1 is also assigned a unique telephone number (050 number) of WLAN. In this mobile device 1, it is possible for the user to select which one of “child number (090 number)” and “representative number (0A0 number)” is used as a transmission number in the 3GPP network. In addition, any number can be received when receiving a call.

  SGSN3 and GGSN4 are nodes constituting the packet network of the 3GPP network. The SGSN 3 is connected to the radio access network side, and the GGSN 4 is connected to an ISP (Internet Service Provider) or a corporate network for connecting to the Internet. Thus, in the 3GPP network, packets can be transmitted / received (= Internet communication) to / from the mobile device 1 through the base station.

  In the present embodiment, the mobile device 1 is connected to the SGSN 3 and the processing server 2 is connected to the GGSN 4 during communication between the mobile device 1 and the processing server 2. That is, the SGSN 3 is configured to be able to control outgoing / incoming calls of the mobile device 1, and the GGSN 4 is configured to be able to control outgoing / incoming calls of the processing server 2. The SGSN 3 holds the subscriber profile 3a as registration information, and when there is a call processing request (call processing request) from the mobile device 1, the SGSN 3 makes a call based on the information of the subscriber profile 3a.

FIG. 4 shows the configuration of a subscriber profile 3a composed of subscriber-specific information.
As shown in FIG. 4, the subscriber profile 3a is composed of “use number flag”, “representative number”, and “child number” for each of the subscribers A, B, C,.
As described above, the “child number” is a unique telephone number (090 number) of the 3GPP network. As described above, the “representative number” is a telephone number that can be used in a communication network other than the 3GPP network (here, WLAN). The “use number flag” is a flag (additional information) that determines whether to use a “child number” or a “representative number” in the 3GPP network. The “use number flag” is selectable by the user, so that the user can make a call using the telephone number by setting the “use number flag” to the phone number normally used. . The “use number flag” can be arbitrarily set and changed by the user by a special number transmission operation. Since the technology for rewriting the profile by sending a special number is common, the details are omitted.

(Operation)
The operation of the communication system is as follows.
FIG. 5 shows a sequence in the communication system when a transmission request is made from a mobile device (UE: User Equipment) 1.
As a call request from the mobile device (UE: User Equipment) 1, the mobile device 1 sends an Activate PDP Context Request to the SGSN 3. ActivatePDP Context Request is a signal (transmission request signal) for requesting the SGSN3 transmission process. Thereby, PDP (Packet Data Protocol) is activated.

  In SGSN3, Create PDP Context Request is sent to GGSN4. Create PDP Context Request is a signal (transmission request signal) that SGSN 3 requests GGSN 4 to perform transmission processing. At this time, the SGSN 3 also sends a child number, a representative number, and a use number flag to the GGSN 4 as MSISDN (MobileStation ISDN number definition) based on the subscriber profile 3a. The MSISDN is unique information including the telephone number of the mobile device 1 and the like.

In GGSN4, it connects to the processing server 2 with the telephone number according to a use number flag. That is, if the use number flag is a representative number (use number flag = representative number), the GGSN 4 notifies the processing server 2 of the connection using MSISDN as the representative number (MSISDN = representative number). In response to this, the processing server 2 sends a connection notification response to the GGSN 4. If the use number flag is a child number (use number flag = child number), the GGSN 4 notifies the processing server 2 of the connection using MSISDN as the child number (MSISDN = child number). In response to this, the processing server 2 sends a connection notification response to the GGSN 4.
In GGSN4, Create PDP Context Response that is a response signal of Create PDP Context Request is sent to SGSN3. In response to this, the SGSN 3 sends Activate PDP Context Accept to the mobile device 1 as a response signal of Activate PDP Context.

  By the sequence as described above in the communication system, the mobile device 1 and the processing server 2 can communicate with each other after a call request from the mobile device (UE: User Equipment) 1 is made. Here, the mobile server 1 that uses the representative number as the telephone number that is normally used, that is, the mobile device 1 whose use number flag is set to the representative number in the subscriber profile 3a, and the processing server that permits communication using the representative number. 2 and the mobile device 1 whose child number is a telephone number that is normally used, that is, the mobile device 1 whose use number flag is set to the child number in the subscriber profile 3a, and the child number It becomes possible to communicate with the processing server 2 that permits the communication by.

With such a communication system, for example, the following communication service can be provided.
First, the user of the mobile device 1 subscribes to a one-number service using the 3GPP network (090 number) and WLAN (050 number). With the contract, the user makes a contract to use the representative number (0A0 number) given by the one-number service as the main. Thereby, on the SGSN 3, the telephone number (090 number) of the 3GPP network is registered as a child number in the subscriber profile 3a, and the number (0A0 number) given in the contract is registered as a representative number. A representative number is set in the use number flag. In addition, in the mobile device 1, the registration or change can be performed on a display screen in a state of being connected to the 3GPP network.

On the other hand, the user registers the representative number in the processing server 2 that is the communication partner of the representative number. For example, registration is performed in the following procedure.
Here, when there is a request (connection) from a specific employee to a specific employee registered in advance in the employee record, the processing server 2 sends a business message to the destination (registered telephone number). Is a server (corporate server) that sends Further, it is assumed that registration to the specific employee is performed on the registration screen, and at that time, the telephone number of the destination of the business message must be registered. For this reason, the user registers a representative number to be a destination in the processing server 2.

  As a result, when there is a connection request (transmission) from the mobile device 1 to the processing server 2, the Create PDPContext Request whose use number flag is the representative number is sent from the SGSN 3 to the GGSN 4, and the GGSN 4 To notify the connection to the processing server 2. Since the representative number is registered in the processing server 2, a connection notification response is sent to the GGSN 4 accordingly. As a result, the GGSN 4 sends Create PDP Context Response, which is a response signal of CreatePDP Context Request, to the SGSN 3, and the SGSN 3 sends Activate PDP Context Accept to the mobile device 1 accordingly. Can be communicated, and a business message is sent from the server to the mobile device 1. The user confirms the business message with the mobile device 1.

  Even when the user of the mobile device 1 subscribes to the one-number service, if the setting is made so that the telephone number (child number) of the 3GPP network is used as the main instead of the representative number (0A0 number), the SGSN3 In the subscriber profile 3a, “child number” is registered in the use number flag. In this case, the user may register a child number in the processing server 2.

(Function and effect)
As described above, the SGSN 3 performs processing with the mobile device 1 while registering the child number and the representative number and the use number flag indicating the telephone number used by the mobile device 1 for communication among them in the SGSN 3. When communicating with the server 2, it is assumed that the processing server 2 registers the telephone number corresponding to the use number flag by transmitting the registration information to the GGSN 4 to which the processing server 2 is connected. Communication between the mobile device 1 and the processing server 2 using one of the child numbers and the representative number, for example, a phone number mainly used by the user of the mobile device 1 becomes possible. In addition, communication using one of the child numbers and the representative number can be performed within the process on the SGSN 3, and communication can be performed while improving the convenience of the communication system.

  For example, as shown in FIG. 6A, when the user wants to make a call using a representative number (0A0 number) that does not need to be aware of the network, the user can connect to the processing server 2 simply by setting the use number flag to the representative number. As shown in FIG. 6 (b), when it is desired to make a call using a child number (090 number), it is possible to connect to the processing server 2 simply by setting the use number flag to the child number. In addition, since only the setting is performed by the SGSN 3, it is possible to connect to the processing server 2 by a child number or a representative number while enhancing the convenience of the communication system.

Note that the above-described embodiment can also be realized by other configurations.
That is, the first embodiment has been described on the assumption that the representative number is used in the 3GPP network 100, but the present invention can be applied even when the representative number is used in the WLAN. In this case, a unique telephone number (050 number) of the WLAN is registered as a child number in the subscriber profile 3a.

  In the description of the first embodiment, the mobile device 1 can communicate with each network by a representative telephone number common to each network while being able to communicate with a unique telephone number for each of a plurality of networks. The SGSN 3 is a communication server that performs communication between a mobile device that is a communication terminal capable of wireless communication and another communication terminal, and includes a unique telephone number and a representative telephone number. Information indicating which telephone number the mobile device communicates with is registered, and on the basis of the registered information, either the unique telephone number or the representative telephone number is used by the mobile device for communication. Thus, a communication server that enables communication between the mobile device and other communication terminals is realized.

SGSN3 is a communication server to which the mobile device is connected during communication between the mobile device and another communication terminal. As registration information, a unique phone number and a representative phone number, and among these phone numbers, Communication in which additional information indicating a telephone number used for communication by a mobile device is registered, and when the mobile device communicates with another communication terminal, the registration information is transmitted to a communication server to which the other communication terminal is connected. A server is realized.
Further, the GGSN 4 connects to another communication terminal by using either a unique telephone number or a representative telephone number of the transmission based on additional information transmitted from a communication server to which the mobile device is connected. Has realized.

(Second Embodiment)
Next, a second embodiment will be described.
(Constitution)
The second embodiment is a communication system to which the present invention is applied.
In the second embodiment, a use number can be registered for each of a plurality of servers connected to the GGSN 4.
FIG. 7 shows a configuration of a communication system in the second embodiment.
As shown in FIG. 7, the GGSN 4 holds an APN (Access Point Name) profile 4a as registration information, and the APN profile 4a is characterized in the second embodiment.

FIG. 8 shows the configuration of the APN profile 4a.
As shown in FIG. 8, the APN profile 4a is composed of “representative number permission / rejection” for each APN (server).
“Representative number permission / rejection” indicates whether or not the server permits the use of the representative number, and “permitted” indicates that the server is permitted to use the representative number. “Reject” indicates that the server does not permit the use of the representative number. Therefore, if “representative number permission / rejection” is “rejection”, this indicates that the server is permitted to use the child number.

(Operation)
The operation of the communication system is as follows.
FIG. 9 shows a sequence in the communication system when a transmission request is made from a mobile device (UE: User Equipment) 1.
As a call request from the mobile device (UE: User Equipment) 1, the mobile device 1 sends an Activate PDP Context Request to the SGSN 3. This activates PDP (PacketData Protocol).
In SGSN3, Create PDP Context Request is sent to GGSN4. At this time, the SGSN 3 also sends a child number, a representative number, and a use number flag as MSISDN (MobileStation ISDN number definition) based on the subscriber profile 3a, as in the first embodiment.
The GGSN 4 connects to the processing server 2 based on the number corresponding to the use number flag and the APN profile 4a.

  That is, in the GGSN 4, the use number flag is the representative number (use number flag = representative number), and “representative number permission / rejection” corresponding to the processing server 2 that notifies the connection is “possible” in the APN profile 4a. ", The connection notification is sent to the processing server 2 with MSISDN as the representative number. In the GGSN 4, the use number flag is a representative number (use number flag = representative number), and “representative number permission / rejection” corresponding to the processing server 2 that notifies the connection is “rejected” in the APN profile 4 a. ", The connection notification is sent to the processing server 2 with MSISDN as the child number. In response to this, the processing server 2 sends a connection notification response to the GGSN 4.

If the use number flag is a child number (use number flag = child number), the GGSN 4 notifies the processing server 2 of the connection using MSISDN as the child number. In response to this, the processing server 2 sends a connection notification response to the GGSN 4.
In GGSN4, Create PDP Context Response that is a response signal of Create PDP Context Request is sent to SGSN3. In response to this, the SGSN 3 sends Activate PDP Context Accept to the mobile device 1 as a response signal of Activate PDP Context.

With such a communication system, for example, the following communication service can be provided.
First, the user of the mobile device 1 subscribes to a one-number service using the 3GPP network (090 number) and WLAN (050 number). In the contract, the user sets to use the representative number (0A0 number) given by the one-number service as the main. Thus, as in the first embodiment, on the SGSN 3, the telephone number (090 number) of the 3GPP network is registered as a child number in the subscriber profile 3a, and the number (0A0 number) assigned in the contract is registered. Is registered as the representative number, and the representative number is registered in the use number flag.

  On the other hand, the processing server 2 limits the use numbers that can be connected. Therefore, “representative number permission / rejection” is set in the APN profile 4a of the GGSN 4 to which the processing server 2 is connected. Here, when permitting a connection with a representative number, set “representative number permission / rejection” to “permitted”, and when rejecting a connection with a representative number or permitting a child number connection, Set “Allow / Reject” to “Reject”.

  Thereby, when there is a connection request (transmission) from the user to the server by the mobile device 1, a CreatePDP Context Request in which the use number flag is a representative number is sent from the SGSN 3 to the GGSN 4, When the processing server 2 permits the connection with the representative number (when the “representative number permission / rejection” of the processing server 2 is “permitted” in the APN profile 4a), the representative server is connected to the processing server 2 by the representative number. Notification of connection. Further, when the processing server 2 rejects the connection with the representative number (when the “representative number permission / rejection” of the processing server 2 is “rejected” in the APN profile 4a), the GGSN 4 Notification of connection to the processing server 2 is made.

  The processing server 2 sends a connection notification response to the GGSN 4 in response to the connection notification from the GGSN 4. As a result, the GGSN 4 sends Create PDP Context Response, which is a response signal of Create PDP Context Request, to the SGSN 3, and the SGSN 3 sends Activate PDP Context Accept to the mobile device 1 in response to this, so Can be communicated, and information is sent from the processing server 2 to the mobile device 1. The user confirms the information with the mobile device 1.

(Function and effect)
As described above, the SGSN 3 registers the child number, the representative number, and the use number flag indicating the phone number used by the mobile device 1 for communication among the phone numbers, and the processing server 2 communicates with the GGSN 4. The APN profile 4a (especially “representative number permission / rejection”) indicating the types of possible mobile device telephone numbers is registered, and when the mobile device 1 and the processing server 2 communicate with each other, the SGSN 3 stores registration information (child Number, representative number and use number flag), and the GGSN 4 uses the SGSN 3 based on the “representative number permission / rejection” of the APN profile 4a and the use number flag in the registration information transmitted from the SGSN 3. Connected to the processing server 2 by one telephone number selected from the child number and the representative number transmitted simultaneously from That. As a result, while the GGSN 4 restricts the types of telephone numbers that the processing server 2 can communicate with, between the mobile device 1 and the processing server 2, one of the child numbers and the representative number, for example, the user Will be able to communicate using telephone numbers that are mainly used.

  In addition, communication using one of the child numbers and the representative number can be performed within the processing on the GGSN 4, and communication can be performed while enhancing the convenience of the communication system. That is, for example, as in the first embodiment, when the user wants to make a call using a representative number (0A0 number) or a child number (090 number), the user only has to set the use number flag accordingly. 2 can communicate with. The processing server 2 can communicate with the mobile device 1 using the desired telephone number type simply by setting “representative number permission / rejection” of the APN profile 4a on the GGSN 4. In other words, in the case of a server that manages users with child numbers as an existing process, even if the user makes a one-number contract and sets a representative number, if the APN profile 4a is rejected, the server is affected. In addition, there is an effect that the server can perform the processing as existing with the child number as before.

(Third embodiment)
Next, a third embodiment will be described.
(Constitution)
The third embodiment is a communication system to which the present invention is applied.
In the third embodiment, the GGSN 4 can receive calls to the mobile device by the representative number. Since the incoming call process with the child number is an incoming call process with a unique number of the network, an embodiment of the incoming call process with the representative number will be described here.
FIG. 10 shows a configuration of a communication system in the third embodiment.
As shown in FIG. 10, the communication system includes an ENUM DNS (Telephone Number Mapping Domain Name Server) 5, and the ENUM DNS 5 holds a number correspondence table 5a as registration information.

FIG. 11 shows the configuration of the number correspondence table 5a.
As shown in FIG. 11, the number correspondence table 5 a has a configuration in which “representative numbers” correspond to “child numbers”.
For example, the number correspondence table 5a is configured based on the subscriber profile 3a held by the SGSN 3.
In addition, in FIG. 12, the structure of the subscriber profile 3a which SGSN3 hold | maintains is shown. The number correspondence table 5a is configured based on the subscriber profile 3a held by the SGSN 3 in this way. The ENUM DNS 5 performs conversion between the “representative number” and the “child number” by using the number correspondence table 5a.
Note that the subscriber profile 3a held by the SGSN 3 may include a “use number flag” as shown in FIG.

(Operation)
The operation of the communication system is as follows.
FIG. 13 shows a sequence in the communication system when an incoming request is made to the mobile device 1 from the processing server 2.
An incoming notification is sent from the processing server 2 to the GGSN 4. At this time, the processing server 2 notifies the incoming call using MSISDN as a representative number.
In GGSN4, DNS query is sent to ENUM DNS5. The DNS query is a signal that realizes conversion between the representative number and the child number.
When receiving the DNS query, ENUM DNS 5 converts the representative number into a child number according to the number correspondence table 5a. Then, ENUM DNS 5 sends DNS resp. (DNS response), which is a response signal of DNS query, to GGSN 4 together with the child number. The GGSN 4 sends a Send Routing Info for GPRS Request to an HLR (Home Location Register) 6.

  The HLR 6 is a node that holds the location information of the mobile device 1. Each SGSN 3 is in charge of a certain area on the communication system, and the HLR 6 knows the area where the mobile device 1 is located (which SGSN 3 can receive calls) as area information. When there is SendRouting Info for GPRS Request as an inquiry about the location of the mobile device 1 from the GGSN 4, the HLR 6 returns the SGSN address of the mobile device 1 to the GGSN 4 by Send Routing Info for GPRS Response as a response signal.

The GGSN 4 sends a PDU Notification Request to the SGSN 3. The PDU Notification Request is a signal (incoming request signal) that the GGSN 4 requests the SGSN 3 to perform incoming processing. Thereby, PDU (Protocol Data Unit) is notified from GGSN4 to SGSN3.
The SGSN 3 sends a Paging Request to the mobile device 1. Paging Request is a signal (calling signal) for calling the mobile device 1 when receiving an incoming call. When receiving a Paging Response as a response signal from the mobile device 1, the SGSN 3 instructs the mobile device 1 to perform an incoming call process with Request PDP Context Activation as a signal for requesting activation of the PDP. Thereafter, a return transmission process from the mobile device 1 is performed.
On the other hand, the SGSN 3 sends a Create PDP Context Request to the GGSN 4, and the GGSN 4 notifies the connection to the processing server 2 with the MSISDN as a representative number correspondingly.

(Function and effect)
As described above, at the time of communication between the mobile device 1 and the processing server 2, the ENUM DNS 5 serving as a communication server to which the processing server 2 is connected (specifically connected via the GGSN 4) has a child number and a representative number. Is associated with the number correspondence table 5a, and the ENUM DNS 5 (or in cooperation with the GGSN 4), when the processing server 2 requests connection to the mobile device 1, the representative number is based on the number correspondence table 5a. It is converted into a child number, that is, a telephone number corresponding to the network is selected to request connection to the mobile device 1. As a result, when the processing server 2 makes a connection request to the mobile device 1, even if the processing server 2 receives an incoming call with a representative number, communication using the child number and the telephone number of the child number suitable for the network among the representative numbers Is possible. In addition, communication using a child number can be performed within the processing of ENUM DNS 5, and communication can be performed while enhancing the convenience of the communication system.
Further, when the processing server 2 receives an incoming call to the mobile device 1 with a child number, it is an incoming call processing with a unique number of the network, so the procedure for converting the representative number into the child number by the number correspondence table 5a is not performed. .

  Through the above processing, the processing server 2 can receive calls using a plurality of telephone numbers. That is, as shown in FIG. 14 (a), when the processing server 2 wishes to receive a call with a representative number (0A0 number), the incoming call notification with the representative number can be received as it is with the GGSN 4, and can be received at the mobile device 1. As shown in FIG. 14 (b), when the processing server 2 wishes to receive a call with a child number (090 number), it can receive the call to the mobile device 1 simply by using the GGSN 4 as an incoming notification with the child number. For example, even when the processing server 2 manages the telephone number of the mobile device 1 that can communicate with either the child number or the representative number, the processing server 2 can receive the incoming call to the mobile device 1 with a telephone number adapted thereto. .

  In the description of the third embodiment, the ENUM DNS 5 (or in cooperation with the GGSN 4) is a communication server that performs communication between a mobile device that is a communication terminal capable of wireless communication and another communication terminal. Among the unique telephone number and the representative telephone number, the telephone number information indicating which telephone number the mobile device communicates with is registered, and based on the registered information, the unique telephone number and the representative telephone number A communication server that enables communication between the mobile device and another communication terminal is realized by using one of them as a telephone number used by the mobile device for communication. In this case, the number correspondence table 5a that performs conversion between the child number and the representative number is information indicating which telephone number the mobile device communicates with among the unique telephone number and the representative telephone number.

  The ENUM DNS 5 (or in cooperation with the GGSN 4) is a communication server to which other communication terminals are connected during communication between the mobile device and other communication terminals. One telephone corresponding to the connection to the mobile station from the registered unique telephone number and representative telephone number when another communication terminal requests connection to the mobile station.
